When the "lost password" feature of a website sends you an email with your original password :/

Hopefully it's not the real code and alerts security that someone is trying to break in.

Reminds me of the post-it notes that's all over the place at most offices. Irony like clockwork every start of the week password reset requests floods the system. Had a few people list every password and password change. 😑

Why is there an A and B?

@Gatgeagent I would have said "to improve security by providing more input possibilities" but I'm not sure anymore ;)

@Gatgeagent In most cases for changing code.

Like:
<code>A = opens door
<masterpass>B <newpass>A <newpass>A = changes code to <newpass>
<masterpass>B <newmp>B <newmp>B = changes masterpass to <newmp>

Can also be more advanced with possibilities to set up validity times for codes, settingsand such, like B01<masterpass> <1/0> = beep for each keypress or not, B02<masterpass> <etc> and so on.

And its not really low security to post the code, because usually, its because the building usage has changed, and the code lock should no longer be there, so they are too lazy to mount down the lock.

It can also be a day code, eg the code lock has no function to keep the door "permanently" open during certain times, so they instead set up a code only valid during day, and affix it to the codelock.

@sebastian does that mean anyone knowing the code can change it?

@juzles No, as you need the mastercode for that.
